Abstract
The invention provides an air knife baffle plate device. The air knife baffle plate device is composed of a zinc pot (1), a furnace nose (5), air knifes (7), air knife rests (10), a baffle plate I (8), a baffle plate II (9), a baffle plate III (12) and a steel strip (13), wherein the air knife rests (10) are arranged on the two sides of the steel strip (13), and symmetrical air knifes (7) are arranged on the bottom of each air knife rest (10). The air knife baffle plate device is characterized in that the baffle plate I (8) and the baffle plate II (9) are suspended to the air knife rests (10) and arranged on the two sides of the air knifes (7), respectively, and further are as long as the air knifes (7). The air knife baffle plate device has the advantages that the baffle plates are added at the two sides of the air knifes (7) so that influence, caused by external wind power, on the air knifes (7) is reduced, and moreover, the phenomenons such as flying cuttings and turbulent flow can be effectively reduced, and the surface quality of a zinc-coated plate can be improved.
Description
Technical field
The present invention relates to the supplementary unit of air knife in pot galvanize unit, especially a kind of novel air knife retaining device.
Background technology
In known Continuous Production Line of Galvanizing by Dipping, conventionally with air knife remove on dezincify pot outlet strip steel surface more than zinc, by control the angle of air knife, highly, wind-force etc. controls zinc coating thickness.In zinc-plated production process, reducing air knife height, reducing gap between the air knife of both sides, breeze up is the effective ways that reduce zinc coating thickness, but after the reduction of air knife height, wind increases, zinc liquid level can produce and fly slag phenomenon, has a strong impact on galvanized sheet plate face quality.
Summary of the invention
For above deficiency, the object of the present invention is to provide a kind of air knife baffle plate device, be by mirror-image arrangement on air knife both sides, hang on air knife frame two baffle plates add baffle plate composition on zinc pot limit, can effectively reduce and fly the phenomenon such as slag, turbulent flow.
Technical scheme of the present invention is achieved in the following ways: a kind of air knife baffle plate device, formed by zinc pot, stove nose, air knife, air knife frame, baffle plate I, baffle plate II, baffle plate III and steel band, two faces of described steel band are respectively equipped with air knife frame, the bottom of air knife frame is equipped with symmetrical air knife, it is characterized in that: on described air knife frame, hang with baffle plate I and baffle plate II, be arranged in air knife both sides, length is identical with air knife.
Described baffle plate III is placed on zinc pot limit, and stove nose is positioned at the both sides of air knife simultaneously.
The present invention, increases baffle plate by the both sides at air knife, reduces the impact of extraneous wind-force on air knife, can effectively reduce and fly slag, and the phenomenons such as turbulent flow, have improved galvanized sheet plate face quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1 is zinc pot, the 2nd, and zinc liquid, the 3rd, sinking roller, the 4th, stabilizing roller, the 5th, stove nose, the 6th, ground, the 7th, air knife, the 8th, baffle plate I, the 9th, baffle plate II, the 10th, air knife frame, the 11st, zinc pot limit, the 12nd, baffle plate III, the 13rd, steel band.
Embodiment
By Fig. 1, a kind of air knife baffle plate device, by zinc pot 1, zinc liquid 2, sinking roller 3, stabilizing roller 4, stove nose 5, ground 6, air knife 7, baffle plate I 8, baffle plate II 9, air knife frame 10, baffle plate III 12 and steel band 13 form, two faces of described steel band 13 are respectively equipped with air knife frame 10, and the bottom of air knife frame 10 is provided with symmetrical air knife 7, all hang with baffle plate I 8 and baffle plate II 9 on each air knife frame 10, be arranged in air knife 7 both sides, length is identical with air knife 7.
Described baffle plate I 8 is moved together with the adjustment up and down of air knife frame 10 with baffle plate II 9, can effectively reduce the impact of extraneous wind-force on air knife 7, guarantees that the wind-force between two air knives 7 and Galvanized Steel Strip 13 is stable, has reduced the generation that flies the phenomenon such as slag and turbulent flow.
Described baffle plate III 12 is placed on zinc pot limit 11; the both sides that are positioned at air knife 7 with stove nose 5 mirror images have formed second layer protection; further reduce the impact of extraneous wind-force; baffle plate III 12 Length Ratio zinc pot limits 11 are short two meters; and being placed on the mid-way on zinc pot limit 11, the neutral gear that expose on both sides facilitates workman to drag for cadmia.
When work; steel band 13 enters zinc pot 1 from stove nose 5; after sinking roller 3 and stabilizing roller 4, go out zinc pot 1 successively; air knife 7 blows out pressure air and wipes zinc unnecessary on steel band 13 off; after the wind that original air knife 7 blows out and extraneous wind interact; zinc liquid level easily produces the slag that flies disorderly spattering; also can on the limit of steel band 13, produce turbulent phenomenon; baffle plate I 8 and baffle plate II 9 form the first layer protective layer now; baffle plate III 12 forms second layer protective layer with stove nose 5, has effectively reduced the impact of extraneous wind-force on air knife 7.
Claims (2)
1. an air knife baffle plate device, formed by zinc pot (1), stove nose (5), air knife (7), air knife frame (10), baffle plate I (8), baffle plate II (9), baffle plate III (12) and steel band (13), two faces of described steel band (13) are respectively equipped with air knife frame (10), the bottom of each air knife frame (10) is equipped with symmetrical air knife (7), it is characterized in that: on described air knife frame (10), hang with baffle plate I (8) and baffle plate II (9), be arranged in air knife (7) both sides, length is identical with air knife (7).
2. a kind of air knife baffle plate device according to claim 1, is characterized in that: described baffle plate III (12) is placed on zinc pot (1) limit, and stove nose (5) is positioned at the both sides of air knife (7) simultaneously.
